i have used javascript.Value from this javascript i have fill textbox.textbox is now fill with value(Ex:200) But problem is ..when this textbox is disable,value in it cannot be inserted into database.if textbox is not disable then value is insert in database.i have to do textbox disable and insert value into database.how i can do this?

Well I am not sure what event this insert statement is taking place so I can't tell what the problem is. But if you are disabling the textbox onblur then it won't get the value to the database because it is essentially invisible after disabling it. Also, your insert statement does not specify columns to insert your values into.
